Register Description
The Device n SOF/EOP Count Register should be written with
the time expected between receiving a SOF/EOP. If the
SOF/EOP counter expires before an SOF/EOP is received, an
SOF/EOP Timeout Interrupt can be generated. The SOF/EOP
Timeout Interrupt Enable and SOF/EOP Timeout Interrupt
Flag are located in the Device n Interrupt Enable and Status
Registers respectively.
The SOF/EOP count should be set slightly greater than the
expected SOF/EOP interval. The SOF/EOP counter decre-
ments at a 12-MHz rate. Therefore, in the case of an expected
1-ms SOF/EOP interval, the SOF/EOP count should be set
slightly greater then 0x2EE0.
OTG Control Register [0xC098] [R/W]
Register Description
The OTG Control Register allows control and monitoring over
the OTG port on Port1A. Note that the D± pull-up and
pull-down bits override the setting in the USB 0 Control
Register for this port.
VBUS Pull-up Enable (Bit 13)
The VBUS Pull-up Enable bit enables or disables a 500Ω
pull-up resistor onto OTG VBus.
1: 500Ω pull-up resistor enabled
0: 500Ω pull-up resistor disabled
Receive Disable (Bit 12)
The Receive Disable bit enables or powers down (disables)
the OTG receiver section.
1: OTG receiver powered down and disabled
0: OTG receiver enabled
Charge Pump Enable (Bit 11)
The Charge Pump Enable bit enables or disables the OTG
VBus charge pump.
1: OTG VBus charge pump enabled
0: OTG VBus charge pump disabled

Count (Bits [13:0])
The Count field contains the current value of the SOF/EOP
down counter. At power-up and reset, this value is set to
0x2EE0 and for expected 1-ms SOF/EOP intervals, this
SOF/EOP count should be increased slightly.
Reserved
All reserved bits should be written as ‘0’.
OTG Control Registers
There is one register dedicated for On-The-Go operation. This
register is covered in this section and summarized in
Table 36.OTG Register
-
VBUS Discharge Enable (Bit 10)
The VBUS Discharge Enable bit enables or disables a 2-KΩ
discharge pull-down resistor onto OTG VBus.
1: 2-KΩ pull-down resistor enabled
0: 2-KΩ pull-down resistor disabled
D+ Pull-up Enable (Bit 9)
The D+ Pull-up Enable bit enables or disables a pull-up
resistor on the OTG D+ data line.
1: OTG D+ dataline pull-up resistor enabled
0: OTG D+ dataline pull-up resistor disabled
D– Pull-up Enable (Bit 8)
The D– Pull-up Enable bit enables or disables a pull-up
resistor on the OTG D– data line.
1: OTG D– dataline pull-up resistor enabled
0: OTG D– dataline pull-up resistor disabled
D+ Pull-down Enable (Bit 7)
The D+ Pull-down Enable bit enables or disables a pull-down
resistor on the OTG D+ data line.
1: OTG D+ dataline pull-down resistor enabled
0: OTG D+ dataline pull-down resistor disabled
